<p>The test pattern to produce.</p>
<p>The Gamut pattern creates a checkerboard pattern of colors at the
edge of the YCbCr gamut and nearby colors that are out of gamut.
The pattern is divided into 4 regions: black, white, red, and blue.
After conversion to RGB, the out-of-gamut colors should be converted
to the same value as their in-gamut neighbors.  If the checkerboard
pattern is still visible after conversion, this indicates a faulty
conversion.  Image manipulation, such as adjusting contrast or
brightness, can also cause the pattern to be visible.</p>
<p>The Zone Plate pattern is based on BBC R&amp;D Report 1978/23, and can
be used to test spatial frequency response of a system.  This
pattern generator is controlled by the xoffset and yoffset parameters
and also by all the parameters starting with 'k'.  The default
parameters produce a grey pattern.  Try 'videotestsrc
pattern=zone-plate kx2=20 ky2=20 kt=1' to produce something
interesting.</p>
